0 a piece of clothing that covers the top part of the body and has a tube-like part covering the neck -- polo yaka, yuvarlak yaka; balıkçı yaka
In the 1950s the black polo neck became a distinctive mark of existentialists.
This is mainly used to achieve the appearance of a polo neck where the fabric would fray, roll, or otherwise behave badly unless sewn.
It can also refer to type of neckline, the style of collar itself, or be used as an adjective (polo necked).
